In the seas of the world where sharks of all kinds are fast disappearing, a deep-diving San Francisco biologist and his colleagues have discovered a new species of shark among the Galapagos Islands.
With its razor-sharp teeth, the shark is well equipped for its role at the top of the ocean’s food web, said John McCosker, the chief of aquatic biology at the California Academy of Sciences who led the discovery. But it’s not much like the feared great white: This one is a modest-size bottom-feeder.
